CVE-2025-26927Network attack vector

Unauthenticated code execution via unrestricted file upload

Published Apr 15, 2025 · Updated Apr 28, 2026

Unrestricted file upload in LiquidThemes AI Hub 1.3.7 and earlier allows remote attackers to upload executable web shells. Patchstack identifies the flaw as an unauthenticated arbitrary upload but has not disclosed the affected handler or the failed file-type validation operation. No credentials or user interaction are required, and a server-executable upload grants code execution in the WordPress site's web-server context.
